I know, could you imagine if a huge club like Barcelona switched away from their traditional red/blue stripes? The world would implode...
...unless it's the star thing they had going on in 97/98, the half/half they had in 99/00, the half/half they had in 08/09, the single string in 12/13, hoops in 15/16, fade thing they had going on in 17/18, checks in 19/20, or the yellow pinstripes next season. That's without mentioning their different-coloured shorts every year...
